Joseph Raaymakers’ confidence couldn’t be higher after a solid audition at Columbus camp.

“The opportunity I was given by the (Blue) Jackets was unbelievable,” said the 20-year-old Knights goaltender, who was sent back to London Monday. “To get the chance to play in an exhibition game and to be around NHLers like (Sergei) Bobrovsky was a true experience.

“It’s crazy to see a guy like that and the preparation he puts into practices and games. He’s a two-time Vezina Trophy winner and he’s never satisfied. He’s always looking to get better.”

The overager will be back in time to face his old team — the Sault Ste. Marie Greyhounds — Friday at 7:30 p.m. at Budweiser Gardens. His Knights mates can’t wait to hear about his experience, especially robbing Knights import and Blackhawks first-rounder Adam Boqvist in a pre-season game against Chicago.

“It was cool playing against him and I wanted to make sure he didn’t score on me,” Raaymakers said. “If he comes back to us, I’ll definitely bug him about that.”

The Chatham native’s return means London will have one of the OHL’s top tandems. While he was in Ohio, Vegas prospect Jordan Kooy kicked aside 24 shots in a season-opening 5-2 victory over rival Windsor last Friday.

“I got to watch a little bit of the game,” Raaymakers said. “Jordan battles and he’s good positionally. He works hard in practice, too. Regardless of who’s in net, we’ll always be there to support each other and pick each other up when we’re down.”

The Knights still are in a roster in flux. First-round pick Liam Foudy remains with the Blue Jackets and is slated to play against the Sabres Tuesday in the American version of Kraft Hockeyville at Clinton, N.Y.

Evan Bouchard (Oilers), Alex Formenton (Senators) and Boqvist are still with their NHL clubs, too.

Raaymakers carried the starting load when he arrived last year and, at one point, made 25 consecutive starts. He seeks a good chunk of the crease in his final major junior season, too.

“I want to play a lot this year and when I get that opportunity, I want to help the team win,” he said. “We all know the end goal is to win a Memorial Cup. It starts one practice and day at a time and build it from there.”
